2 Claims.

This invention appertains to new and useful improvements in appliances for dentist offices and more particularly to an automatic apparatus for maintaining the usual stationary tumbler constantly filled to a certain level and having an overflow serving as the dentists cuspidor flusher.

The principal object of the present invention is to provide means whereby the usual tumbler from which the dentist obtains water for his mouth syringe may be filled to a definite level and kept at this level without personal attention and wherein the overflow beyond this level is utilized as a flush for the patients cuspidor.

These and various other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawing:-

Figure 1 represents a side elevational view of the apparatus with parts in section.

0 Figure 2 represents a sectional view taken substantially on the line 22 of Figure 1.

Referring to the drawing wherein like numerals designate like parts, it can be seen that numeral 5 represents a tank having a removable cover 6.

A water supply line 1 extends to the bottom of this tank 5 and has the shut-ofi valve 8 therein.

Extending from the bottom of the tank 5 is the conduit 9 which extends to the bottom of the fixed tumbler Ill and from the bottom of the tumbler In a connection I I can be provided for connection to another tumbler and so on to as many as desired in an office.

From the upper portion of the tank 5 a pipe l2 extends downwardly to the perforated cir- 'cular tube l3 in the patients cuspidor [4. It can now be seen, that water admitted to the tank 5 will fill the tank to the level [5 and overflow through the pipe I2 to flush the cuspidor I4. Siinultaneously water will pass from the tank 5 through the conduit 9 to the tumbler in, but the water admitted to the tumbler It will rise no higher than the level l6 which is the level IS in the tank 5.

While the foregoing specification sets forth the invention in specific terms, it is to be understood that numerous changes in the shape, size 10 and materials may be resorted to without departing from the spirit and scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed is 5 1. A dentist appliance comprising a tank having a water inlet at its bottom, a water outlet adjacent its top, a pipe extending from the water outlet, a cuspidor having a perforated spray tube therein connected with the said pipe extending 2 from the water outlet, a water outlet pipe from the bottom of the tank, a stationary tumbler to which the water outlet from the bottom of the tank connects.
